International audience. IL-1 and prostaglandin (PGE2, PGF2 alpha, TXB2) concentrations, PLA2 activity, neutral protease activity, and collagenase activity specific for types I and II collagen were determined in the SF of patients suffering from RA, before and after treatment with TA. Active and latent forms of protease and collagenases were regularly detected but were unrelated to IL-1, PLA2, and PGE2. TA induced a significant decrease in tested eicosanoids but IL-1, PLA2, and proteases were unchanged.IL-1 and prostaglandin (PGE2, PGF2 alpha, TXB2) concentrations, PLA2 activity, neutral protease activity, and collagenase activity specific for types I and II collagen were determined in the SF of patients suffering from RA, before and after treatment with TA.
